Position: Scientist Field: Mass and related quantities Organisation: Measurement Standards Laboratory

Chris studied at Victoria University, completing a BSc (Hons) in Physics and then a PhD in Professor David Beaglehole’s newly established research programme in condensed matter physics.

“It took a while to start my PhD research because we had to build the whole laboratory from scratch, but I learnt many useful skills, and my project on the optical properties of amorphous and crystalline magnesium-bismuth alloys gave some very interesting results.”

Keen to apply himself to work that had a practical relevance, Chris then worked as a scientist at the Physics and Engineering Laboratory (PEL) of the DSIR, developing new pressure standards. This turned out to be a good move, since international co-operation in metrology was about to expand rapidly, driven largely by the globalisation of trade and by advances in technology.

While metrology in pressure and mass remain his specialist areas, Chris has been active in a range of other metrology areas including density, length, vibration and flow. He was a guest researcher for a year in the vacuum group at the National Physical Laboratory, UK, and for 8 months in the pressure group at the National Bureau of Standards, USA (now NIST).

Chris has also been involved in the management and politics of metrology. During the restructuring of New Zealand science from the DSIR to Crown research institutes in 1992, he helped to write new measurement standards legislation that, amongst other things, created a national metrology institute – the Measurement Standards Laboratory of New Zealand (MSL). In 1999, as the Director of MSL, Chris was involved in the negotiation and signing of a global arrangement for the mutual recognition of calibration and measurement certificates (CMCs) issued by national metrology institutes. This arrangement has now been signed by over 80 countries or economies. Chris currently chairs the international working group that oversees the review and approval of CMCs for mass and related quantities.

The negotiation process was an eye-opener for me. It was highly political and made me realise that scientists need to be able to sell and negotiate as well as deliver on the science.

In his spare time, Chris likes to enjoy New Zealand’s countryside either on foot or on an off-road bicycle.
